Hybridization of Rydberg orbitals by molecule formation — •Anita Gaj, Alexander T. Krupp, Philipp Ilzhöfer, Thomas Schmid, Robert Löw, Sebastian Hofferberth, and Tilman Pfau — University of Stuttgart, Stuttgart, Germany

The bond in ultralong-range Rydberg molecules results from scattering between a Rydberg electron and ground state atoms in an ultracold gas. In our setup we can selectively excite rovibrational states of D-state molecules. We study their binding energies and the shape of the binding potential at the crossing of two mj states in an external electric field. The degeneracy of the electronic orbitals leads to stronger binding energies and new symmetries of the bound molecular states. As a consequence the Rydberg orbitals hybridize due to the molecular bond.
